Is it possible to connect Load direct to battery?

I have a simple Solar setup, using MPPT 75 I 15, a Siemens Solar Panel M110-24 and a 12V110Ah battery.

I want to add more battery capacity, but that is another issue, so I wounder if I can connect an Inverter 12Vdc to 230Vac-700W direct to battery?

this is because the MPPT75 I 15 has a máx load output of 15Amp (180W) and the inverter will consume much more. The MPPT 75 I 15 will shutdown port LOAD when battery reach low battery level. As the inverter has a wired powerOn control, the battery will be protected since the wired powerOn from inverter is connected to port LOAD. When port LOAD is off, inverter is off.

Is it possible? thanks in advance, best regards.

This is exactly what is also described in the manual of the MPPT.
